sounds to me they are trying to line their pockets. I have removed broken studs by welding a washer to the stud and then;) a nut to the washer and usually works better than you think. I thinking just heating the stud up helps free it. Also you only can do this with a Mig welder.
Every broken exhaust manifold bolt that I have seen on an ISL/ISC has been broken below the surface of the head. Also given that most coach arrangements do not allow a straight on view of the hole, I am not sure how you accomplish this?
